A fan member 33 is secured to a shaft 34 which A plate member I4 is secured within the frame is iournalled in a bearing member 35 secured as 5 shown in Figure 1 between the two vertical bars The fan 33 is of a diameter substantially equal to or slightly less than the diameter of the opening l6 and has at least a portion of the blade structure thereof projecting forwardly through the opening it. The bearing 35 is provided with a rearwardly projecting central portion 36 and a lubricating fitting 31 is secured to the bearing portion 36. to the shaft 34 between the fan 33 and the vertical bars 23 and the pulley 33 is rotated by means of a belt 39 which engages about the pulley 33 and also about a driving pulley 40 secured to a motor shaft 4i rotated by a motor 42. The belt 39 may be substantially V-sbaped in transverse section and the two pulleys 33 and 43 may be provided with V-shaped pulley grooves.

The motor 42 is secured to the frame structure 3 comprising the vertical bars 23 and the horizontal bars 24 by means of a rearwardly extending bracket 43 which is secured to the rear side of the two frame bars adjacent the lower ends thereof.

a In the use of this fan mounting structure, the frame it) is adapted to be mounted in the desired opening and the motor 42 connected to a suitable source of electric current supply. The resilient mounting comprising the frame formed of the vertical and parallel bars 23 and the horizontal parallel end bars 24 provides an exceedingly simple mounting means whereby the motor and fan structure is yieldably supported for rotation of the fan 33 in the opening it of the plate 14. a

The springs 30 will not only yieldably support the fan and motor frame structure against vertical movement but the securing bolts attaching the springs 21 and 30 to the fan and motor frame structure and the supporting bars l1 and 20 will yieldably hold the fan and motor frame structure against lateral movement relative to the supporting bars I! and 20; In this manner, it is not necessary to provide additional supporting means connecting the fan and motor. frame structure to the side bars I! of the frame I I.

What I claim is:

1. In a ventilating fan mounting." an upstand-Q ing front frame formed of a top, a bottom and a pair of side frame members secured together, upi fixed to the sides of the:

frame and aligned throughout with the top and and extending in opposite directions from the ends of the vertical bars aligned with and spaced 2. In a fan mounting, an upstanding substantially square front frame adapted to have secured thereto means to provide an air passage, an up- ,narrow substantially rectangular rear for suspending a fan and for supporting the operating means for the fan, said rear frame being disposed on its lower end and of less height than thereto means the front frame, said rear frame being spaced rearwardly of and arranged substantially centrally with respect to said front frame, upperv and lower horizontally disposed spaced parallel supwith thetop and botconvergent end portions front frame and aligned with the top and bottolnof the front frame, said elements including intermediate portions ar-' ranged in parallel relation. relative to the top and bottom of the front frame and aligned in I spaced relation with the top and bottom of the rear frame, springs for connecting the intermediate portion of said upper element to the top of theirear frame, and springs for connecting'the intermediate portion of the lower element to the bottom of the rear frame,
